Sergeant Guy Uweda of the Elk Grove Police Department said the robber entered the store around 10:42 p.m., flashed a silver automatic handgun and demanded cash. The store employee complied with the robber's demands and the individual fled with an undisclosed amount of money.

The robber was described as a man wearing a ski mask and a black hooded sweatshirt. He was listed as approximately 5'10" tall and 160 pounds.

Uweda said police would investigate surveillance footage from cameras at nearby businesses to get a more thorough description of the perpetrator.
